Our analysis shows that PA sources contribute 5.26% to visibility impairment at Dolly Sods and the largest contribution from a single unit is 0.58% from Allegheny's Hatfield Ferry Unit 32, with next two largest contributors also being units at Hatfield Ferry, each with a contribution of 0.57%.

I believe I may have spoken to Doris about it before, but I wanted to confirm that Virginia and West Virginia are not identifying Pennsylvania as an important contributor to visibility impairment in their Class I areas and are not requesting that Pennsylvania participate in their state

...IMPROVE monitor locations, natural background and baseline conditions for Dolly Sods, Otter Creek, Shenandoah, and James River Face. Some of the information I got from your powerpoint, some from the VIEWS database. Would you prefer that I cite VIEWS as the source or correspondence with you? I think the FLMs might also ask us to include calculations of the uniform rate of progress for these 4 VISTAS areas. And, just to confirm, the Dolly Sods monitor is the representative monitor for Otter Creek, correct? Thanks again, Nancy

Hey Nancy, First off, I apologize for the size of this file. VISTAS does much of their information sharing using PPT charts and graphs, and I think this file has the most recent data available for the VA sites. We are using the new improve equation, and there are graphs showing new vs old, as well as the changes to the natural condition numbers. VISTAS has a large number of Class I's, so they lumped the Class I's into groups by geography and other similarities. Since Shen and JRF are lumped into an Appalachian region in VISTAS, the presentation also has Dolly Sods info in it. I am still going through the torture of reasonable progress, and I know Laura has a jump on me with the SIP development, so I think she can tell both of us if these are indeed the most recent numbers. Let me see what else I can dig up for you. On a related note, have you guys made any changes to your 2018 SO2 inventory based on the controls you may be expecting due to your Hg regulation? I asked Arleen Shulman about this a while back, and it sounded like you guys haven't made any changes to your 2018 inventory. Just wanted to double check, though.

We had a conference call with the FLMs at the end of August. They asked us to add information for Virginia and West Virginia Class I areas that our emission might affect. For example, our draft SIP included a table of MANE

- VU Class I areas and the IMPROVE monitors that represent them. The next table contains 20% Best and 20% Worst visibility conditions for Baseline and Natural Conditions. I can get most of the data from VIEWS, but when I got to that 2nd table, I realized that I don't know what adjustments you made to natural conditions or if you are using the default or alternative methods. I'm attaching the 2 tables in a word document, so you can see what I'm talking about. Do you have this information easily available, or could you point me to a VISTAS report? Also, I tried to find Fred Durham's email address to ask him about WV's areas but couldn't find it. The WV website doesn't seem to be working right now. Do you have it? Thanks for your help!
